Jan 01, 1992 Crushed lightweight aggregate concrete (LWAC) can also be used as an aggregate in concrete (recycled LWAC-aggregate) (European Union Brite EuRam III, 2000).Crushed waste lightweight concrete block has been used successfully as recycled aggregates for making lightweight alkali-activated concrete using NaOH, sodium silicate and fly ash (Posi et al., 2013) with acceptable

What Is Lightweight Aggregate Concrete And Its Uses?

The lightweight aggregate is a kind of coarse aggregate which is used in the production of lightweight concrete products like concrete block, structural concrete, and pavement.. The shape of the lightweight aggregate used in concrete can be cubical, rounded, angular, or of any other shape.The shape and texture can directly affect its workability. The compressive strength level which is

Moisture in Lightweight Structural Concrete Roof Decks

Lightweight structural concrete uses lightweight, porous aggregates such as expanded shale, which will absorb about 5 to 25 percent moisture by weight. Lightweight aggregate needs to be saturated with moisture—it’s often stored in ponds—before mixing. As a result, lightweight structural concrete
